Flosser "Ultra" bulbs are rated for up to 90% more light output than standard H4 bulbs while maintaining the stock 55 watts. This is accomplished via precision manufacturing that allows these bulbs to operate at the upper tolerance limit, giving more light output at the same rated power.
H4 bulbs are dual wattage and have two filaments, one for low beam one for high beam.
We know of the following applications for this bulb:
- MkIV Jetta E-Codes main beam/high beam bulb. WILL NOT FIT FACTORY JETTA LIGHTS.
- 2012+ Beetle Main/High beam bulb.
